OK, part 2, so this is the smallest SSD RAID NAS I could make for a Raspberry Pie 4 and ZFS use

So this is the smallest format I can see currently out there. Yes I bent the rules and got rid of some standards but that is the point right! Nope it is USB base so not fast like NVMe or SSD SAS bus but can be pretty large disk size and can go up to RAID 5 configurations with TrueNAS or ZFS build outs. Counting the I/O USB cards it is smaller then a Raspberry-Pie case housing by far. So this will do RAID 1 or higher up to five to eight SSD disks or SATA/NVMe daughter cards drives but that make the setup a little bigger. hope you like and please like if possible.
Next up is part 3, showing how to build the R-pie OS out to use this small disks array
Vendors I used for my parts:
Hex extensions
USB to SATA converters
USB to SATA edge cards
